1. 1377, "to serve as evidence of," from L. testificari "bear witness," from testis "witness" (see testament) + root of facere "to make" (see factitious). Biblical sense of "openly profess one's faith and devotion" is attested from 1526.
2. PIE word
3. *tréyes
4. From Middle English testifien, borrowed from Old French testifier, from Latin testificārī (“to bear witness”), from testis (“a witness”) + facere (“to make”). See -fy. See: Latin 'testificor'.
